Health Considerations for Individuals Engaging in Extreme Endurance Events and Ultra-Marathons
Extreme endurance events and ultra-marathons are physically demanding activities that can have significant impacts on various body systems. This synthesis presents key insights from multiple research papers on the health considerations for individuals participating in these events.
Key Insights
-
Cardiovascular Health:
- Ultra-endurance running can lead to right ventricular dysfunction, increased risk of arrhythmias, and hypertension .
- Participation in ultra-marathons is associated with acute reductions in large artery compliance, which may affect cardiovascular function.
- Conventional cardiovascular risk factors, such as hypertension and dyslipidemia, are common among ultra-endurance runners, and early life participation in competitive sports may reduce these risks.
-
Respiratory Health:
- Ultra-marathon running can cause significant post-race reductions in pulmonary function, although these changes are rarely clinically significant in individuals with healthy baseline parameters .
- Respiratory muscle fatigue is more prevalent following marathons compared to ultra-marathons, potentially affecting postural stability and increasing injury risk.
-
Renal Health:
- Ultra-endurance athletes are at risk of acute kidney injury (AKI), which can be exacerbated by the use of non-steroidal anti-inflammatory drugs and conditions like exertional rhabdomyolysis and exercise-associated hyponatremia .
-
Nutritional Considerations:
- Managing energy and fluid balance is crucial, as ultra-endurance events can lead to significant energy deficits and fluid losses, increasing the risk of hypohydration and exercise-associated hyponatremia .
- Athletes should follow individualized nutritional strategies to meet caloric demands, enhance fat oxidative capacity, and maintain electrolyte balance.
-
Musculoskeletal Health:
- Ultra-endurance running can lead to a decrease in both fat and skeletal muscle mass, and athletes need to manage sport anemia and gastrointestinal discomfort, especially under extreme environmental conditions.
-
Cognitive and Neuromuscular Function:
- Participation in ultra-marathons is associated with marked impairments in cognitive performance, including slower reaction times and reduced memory test performance, which are linked to changes in cardiovascular function.
- Neuromuscular fatigue, influenced by central and peripheral factors, plays a critical role in performance and pacing strategies during ultra-marathons.
Conclusion
Engaging in extreme endurance events and ultra-marathons poses several health considerations, including impacts on cardiovascular, respiratory, renal, musculoskeletal, and cognitive functions. Proper management of nutrition, hydration, and training strategies is essential to mitigate these risks and enhance performance. Further research is needed to better understand the long-term health implications and to develop effective risk stratification and management practices for athletes.
